Description

Technical Field

[0001] This utility model relates to the field of energy-saving lamp technology, specifically to an energy-saving lamp that is easy to dissipate heat. Background Technology

[0002] LED tubes (also known as LED fluorescent tubes) are lighting devices that use light-emitting diodes (LEDs) as their light source. They are designed to replace traditional fluorescent lamps and are characterized by high efficiency, energy saving, environmental friendliness, and durability. They are widely used in various indoor lighting scenarios.

[0003] A Chinese utility model patent with publication number "CN221424826U" discloses an energy-saving lamp tube with easy heat dissipation, relating to the field of lamp tube design technology. It includes a connecting end, a lamp holder, and a lamp cover. The lamp cover is mounted on the top of the lamp holder, and connecting ends are installed at both ends of the lamp holder and the lamp cover. A substrate is fixed to the inner wall of the lamp holder, and an LED circuit board is provided on the surface of the substrate. The substrate has two rows of heat-conducting holes, and a heat dissipation part is provided at the bottom of the substrate at the location of the heat-conducting holes. This utility model, by setting up heat-conducting holes and a heat dissipation part, ensures that during daily use, a small portion of the heat generated by the LED circuit board is transferred to the substrate, while most accumulates inside the lamp cover. The heat is then conducted to the inside of the copper tube through the heat-conducting holes. Simultaneously, the silicone pad inside the copper tube enhances heat absorption and conduction capabilities. The copper ring plate located outside the lamp holder can then quickly dissipate the heat, effectively improving the heat dissipation effect of the lamp tube without affecting its sealing performance, preventing dust and water ingress that could damage electronic components.

[0004] However, the LED tubes in the aforementioned patents are relatively inconvenient to disassemble and assemble, which makes it inconvenient for users to replace the LED strips or tubes when they are damaged. Utility Model Content

[0005] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides an energy-saving lamp tube that is easy to disassemble, assemble, and maintain, and has good heat dissipation.

[0006] The technical solution adopted by this utility model is as follows: This utility model provides an energy-saving lamp tube with easy heat dissipation, including a lamp body and end caps. Two sets of end caps are provided, and the two sets of end caps are slidably sleeved on both ends of the lamp body. The lamp body and the end caps are connected by a modular connection.

[0007] The lamp body includes an aluminum shell, a lampshade, a heat-conducting substrate, and LED beads. The aluminum shell has a retaining strip, and the lampshade has a second retaining groove. The retaining strip is slidably engaged in the second retaining groove. The aluminum shell has a first retaining groove, and the heat-conducting substrate is slidably engaged in the first retaining groove. The LED beads are disposed on the heat-conducting substrate, and the heat-conducting substrate is also printed with conductive lines that provide current paths for the LED beads. The bottom of the aluminum shell is recessed to form a boss, and a heat-conducting rod is provided on the boss, which contacts the heat-conducting substrate.

[0008] Furthermore, the aluminum outer shell is provided with a connecting piece, the connecting piece is provided with a card, the card is provided with a card head, the end cap is provided with a slot, and the card head is engaged in the slot.

[0009] Furthermore, the card head is provided with an inlet bevel.

[0010] Furthermore, heat dissipation fins are provided on the outer wall of the aluminum casing.

[0011] Furthermore, a wiring port is provided on one of the end caps.

[0012] Furthermore, thermally conductive silicone is applied to the contact positions between the thermally conductive substrate and the thermally conductive rod, as well as the contact positions between the thermally conductive substrate and the aluminum shell.

[0013] Furthermore, a sealing gasket is provided inside the end cap.

[0014] Furthermore, the heat-conducting substrate and the heat-conducting rod are made of aluminum alloy or copper.

[0015] The beneficial effects of this utility model using the above structure are as follows: This solution facilitates the disassembly and assembly of the end caps, lampshade, and heat-conducting substrate on both sides, making it easier to repair when the lamp tube is damaged; This solution helps to improve heat dissipation by setting up a heat-conducting substrate, heat-conducting rod, aluminum shell, and heat dissipation fins, thus avoiding overheating and damage to the LED beads.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] like Figures 1-8 As shown, this utility model discloses an energy-saving lamp tube with easy heat dissipation, including a lamp body 1 and an end cap 2. The end cap 2 is provided in two sets, and the two sets of end caps 2 are respectively slidably sleeved on both ends of the lamp body 1. The lamp body 1 and the end cap 2 are connected by a block-and-disassemble method. One set of end caps 2 is provided with a wiring port 18. A sealing gasket 19 is provided inside the end cap 2.

[0029] The lamp body 1 includes an aluminum shell 3, a lamp cover 4, a heat-conducting substrate 5, and LED beads 6. The aluminum shell 3 is provided with a retaining strip 9, and the lamp cover 4 is provided with a second retaining groove 10. The retaining strip 9 is slidably engaged in the second retaining groove 10. The aluminum shell 3 is provided with a first retaining groove 8, and the heat-conducting substrate 5 is slidably engaged in the first retaining groove 8. The LED beads 6 are disposed on the heat-conducting substrate 5. The heat-conducting substrate 5 is also printed with conductive lines that provide current path for the LED beads 6. The bottom of the aluminum shell 3 is recessed to form a boss 11, and a heat-conducting rod 7 is provided on the boss 11. The heat-conducting rod 7 contacts the heat-conducting substrate 5. The outer wall of the aluminum shell 3 is provided with heat dissipation fins 17. The contact positions between the heat-conducting substrate 5 and the heat-conducting rod 7, as well as the contact positions between the heat-conducting substrate 5 and the aluminum shell 3, are coated with thermally conductive silicone. The heat-conducting substrate 5 and the heat-conducting rod 7 are made of aluminum alloy or copper.

[0030] The aluminum shell 3 is provided with a connecting piece 12, the connecting piece 12 is provided with a card 13, the card 13 is provided with a card head 14, the end cap 2 is provided with a slot 15, and the card head 14 is snapped into the slot 15; the card head 14 is provided with an guide slope 16.

[0031] In practical use, the LED beads 6 generate heat when they work. Some of the heat is directly conducted to the aluminum shell 3 and the heat sink 17 through the thermal conductive substrate 5, and some of the heat is conducted to the aluminum shell 3 and the heat sink 17 through the thermal conductive rod 7 through the thermal conductive substrate 5. This helps to improve the heat dissipation efficiency and effect. Applying thermal conductive silicone can better ensure the heat conduction effect between the thermal conductive substrate 5 and the aluminum shell 3, as well as between the thermal conductive substrate 5 and the thermal conductive rod 7.

[0032] When the lamp needs to be repaired, simply remove the lamp and then press the clip 14 inward to move the clip 14 out of the slot 15. Then the end cover 2 can be removed. After removing the end cover 2, simply slide the lamp cover 4 and the heat-conducting substrate 5 to remove them. The operation is simpler and more convenient, making it easier to repair the lamp.

[0033] In summary, this design facilitates the disassembly and assembly of the end caps 2, lampshade 4, and heat-conducting substrate 5 on both sides, making it easier to repair the lamp tube when it is damaged. The design also improves heat dissipation by incorporating the heat-conducting substrate 5, heat-conducting rod 7, aluminum shell 3, and heat dissipation fins 17, thus preventing the LED beads 6 from overheating and being damaged.
